The Adventures of Robin Hood (1938) on Netflix

In the late twelfth century, King Richard the Lionhearted of England is fighting in the Holy Crusades, leaving the Regency of the Kingdom to his trusted friend, Longchamps. When Richard is captured by Leopold of Austria, Richard's brother, the treacherous Prince John, with help from his supportive Norman barons and his primary henchman Sir Guy of Gisbourne, seizes control of the Regency. Under the guise of getting money to free Richard, John, in pillaging from the Saxon commoners, uses the money instead to fatten his own coffers in gaining control of the throne. The Saxons turn to one of their own, Sir Robin of Locksley - also known as Robin Hood - who, often recklessly, fights on their behalf against Norman authority in an effort to restore what is rightfully the Saxons until Richard's return, Richard to who Robin is loyal. As such, Robin is viewed as an outlaw by Prince John and Sir Guy. Robin's refuge is Sherwood Forest, where he recruits men to fight for what he believes is right. Generally matching Robin's happy-go-lucky temperament, that band of merry men includes Will Scarlet, John Little (renamed Little John because of his hulking physical size), and Friar Tuck. Also seeing Robin and his men as outlaws is Lady Marian Fitzswalter, a Norman and a royal ward. It isn't until Marian meets Robin and sees first hand what he is doing that she changes her allegiances. Prince John and Sir Guy hope to use what they see as the growing attraction between Robin and Marian to capture Robin and sentence him to death. Robin and Marian, the latter she believes clandestinely, work against Prince John and Sir Guy until King Richard's return, when they hope all will be right with England. But the return of King Richard, if it does happen, does not automatically restore him to the throne, especially if Prince John can crown himself king in Richard's absence.
